       5. The device of  claim 1 , further comprising: 
       a valve including a side wall, the valve being adaptable to interpose the side wall between the intake tube and the reservoir.  
     
     
       6. The device of  claim 1 , further comprising: a valve including a vent port, the valve being adaptable to interpose the vent port between the expellant port and the reservoir, and to interpose a side wall between the intake tube and the reservoir. 
     
     
       7. The device of  claim 1 , wherein the reservoir comprises a rigid bottle. 
     
     
       8. A device for dispensing chemical product, comprising: 
       a reservoir;  
       a collapsible container configured to be inserted into the reservoir;  
       a rotatable valve cover, configured to be removably attached to the reservoir, the valve cover including an intake tube connected to receive fluid from an external source, a piercing tube configured to be inserted through a portion of the collapsible container inserted in the reservoir when said valve cover is attached to the reservoir, and an expellant port connected to conduct chemical product from the piercing tube;  
       a valve including a rinse connection port, the valve being adaptable to interpose the rinse connection port between the intake tube and the reservoir and to interpose a vent port between the expellant port.  
     
     
       9. A device for dispensing chemical product, comprising: 
       a reservoir;  
       a collapsible container configured to be inserted into the reservoir;  
       a rotatable valve cover, configured to be removably attached to the reservoir, the valve cover including an intake tube connected to receive fluid from an external source, a piercing tube configured to be inserted through a portion of the collapsible container inserted in the reservoir when said valve cover is attached to the reservoir, and an expellant port connected to conduct chemical product from the piercing tube;  
       a valve including a rinse connection port, the valve being adaptable to interpose the rinse connection port between the intake tube and the reservoir and to interpose the vent port between the expellant port.  
     
     
       10. A system for dispensing a product, comprising: 
       a reservoir for receiving a collapsible container;  
       a valve cover, configured to be removably attached to the reservoir, the valve cover including an intake tube connected to receive fluid from an external source, a piercing tube configured to be inserted through a portion of the collapsible container received by the reservoir when said valve cover is attached to the reservoir, and an expellant port connected to conduct product from the piercing tube; and  
       a valve including a vent port, the valve being adaptable to interpose the vent port between the expellant port and the reservoir.  
     
     
       11. A device for dispensing a product from a collapsible container by applying external pressure to the collapsible container thereby expelling the product through an application, comprising: 
       a pressure bottle having a receptacle for receiving a collapsible container;  
       a sprayer cover, removable affixed to the pressure bottle, comprising:  
       a water intake tube;  
       a rinse tube; and  
       a hollow piercing tube, the piercing tube configured to be inserted through a portion of the collapsible container inserted in the receptacle when said sprayer cover is affixed to the pressure bottle;  
       an applicator wand; and  
       a valve, adaptable to plurality of configurations, including a first configuration connecting the water intake tube between an external water source and the receptacle and connecting the hollow piercing tube between the collapsible container and the applicator wand.
